Signal Jamming Prosecutions
📡 Signal Jamming Prosecutions: Overview
Signal jamming refers to the deliberate transmission of radio frequency signals that interfere with or block authorized communications such as mobile phone signals, GPS, Wi-Fi, or emergency service communications. It is illegal because it disrupts lawful communication channels and can cause serious safety risks.
⚖️ Legal Framework
The main UK laws governing signal jamming are:
Wireless Telegraphy Act 2006
Makes it an offence to use or possess radio equipment capable of causing harmful interference (including jammers) without a licence.
Telecommunications Act 1984
Prohibits interference with telecommunications systems.
Regulation of Investigatory Powers Act 2000 (RIPA)
Addresses interception and interference of communications.
Misuse of Drugs Act 1971 (in cases involving jamming devices used to obstruct law enforcement).
Road Traffic Act 1988 (indirectly related where jamming interferes with emergency communications).
